technician a says that drum brakes can fail to slow the vehicle if driven through deep water. technician b says that when drum brakes get hot, the brake pedal will drop because the drum expands away from the shoes. which technician is correct?
technician a only
technician b only
both technicians
neither technician

Explanation:

For Question 3: Starwheel adjusters use left/right-handed threads on opposite sides to ensure proper adjustment direction, so Technician A is correct. A pawl engages the starwheel's teeth to lock or control its movement, so Technician B is also correct.
For Question 4: Deep water can wet drum brake components, reducing friction and causing temporary failure (Technician A correct). Hot drums expand outward from brake shoes, increasing the gap and requiring more pedal travel (dropping pedal, Technician B correct).

Answer:

Question 3: Both technicians
Question 4: Both technicians
